Space Weather News for Oct. 24, 2011

CME IMPACT: A coronal mass ejection (CME) hit Earth's magnetic field on Oct. 24th around 1800 UT (2 pm EDT).

The impact strongly compressed our planet's magnetosphere and may have exposed geosynchronous satellites to solar wind plasma. Mild to moderate geomagnetic storms are possible in the hours ahead as Earth's magnetic field continues to reverberate from the hit. Sky watchers in Scandinavia, Canada, and northern-tier US States should be alert for auroras, especially during the hours around local midnight.
